My friend Carolyn inspired me to make these, hence the name! It took me ages to work out the perfect pattern, I nearly gave up as I wasn't in a very patient mood this weekend - I'm glad I persevered though, they're really fun to make.
I got the pattern from here. The invisible decreasing she uses is really great.
To make them smaller or bigger, simply make less or more increasing and decreasing rounds - also, reduce the rounds in the middle; so for the small bauble I made the initial six stitches, increased for two rounds, then made three rounds of single crochet, then decreased for three rounds.
